Appcation filed May 24. 1913. Serial No. 769,652.

To all whom t may concern Be it known that I, PETER A. SOLEM, a citizen of the United States, residing at Cincinnati, in the county of I-Iamilton and State of Ohio, have invented certain new and useful Improvements in Woodworking Machinery, of which the following is a specification.

My invention relates to wood-working machinery, such as planing machinery and planing and matching machinery, the latter term including so-called flooring machines, and it is the object of my invention to provide novel means of substantial form and simple construction whereby the countershaft for driving the cutter-head or cutterheads is adjusted into parallelism with the cutter-head shaft or shafts, said means providing ready means for stretching the belts between the countershaft and cutter-head shaft or shafts; further to provide an independent countershaft frame spaced from the main frame-of the machine, and novel relations between the main frame and countershaft; further, to provide a machine of the character mentioned with novel belttightening mechanism; and the invention will be further readily understood from the following description and claims, and from the drawings, in which latter:

Figure 1 is a side elevation of an exemplified planing and matching machine, having my invention applied in connection therewith. Fig. 2 is a plan view of the same. Fig. 3 is a vertical section on the line 3 3 of Fig. 2. Fig. 4 is a detail in section on the line 4 of Fig. 2, showing the means for mounting the countershaft bearing. Fig. 5 is a detail in section on the line 5 5 of Fig. 2, showing the adjusting means on the countershaft frame for the side contact arm. Fig. 6 is a detail in side elevation of one of the tightener pulley arms for the belts for the side-heads, showing the mounting of the saine, and showing its supporting shaft in cross-section on'the line 6-6 of Fig. 3. Fig. 7 is a detail of the same in section on the line 7-7 of Fig. 6. Fig. 8 is a detail of the same on the line 8-8 of Fig. 6; and, Fig. 9 is a detail in section on the line 9-9 of Fig. 2, showing the means for mounting the tightener pulleys for the belts of the horizontal cutter-heads.

I have exemplified my invention in connection with a so-called planing and matching machine of flooring machine type, employing an upper cutter-head 11, a lower cutter-head 12, and side cutter-heads 13, 14. Suitable feeding means for the machine are employed, exemplified as a pair of feed-rolls 15, 16, of which a suitable number may be employed, suitably mounted and adjustable in the main frame 17 of the machine. The upper cutter-head is mounted on a shaft 18 journaled in bearings 19 on a saddle 2O adjustable in suitable manner up and down on uprights 21 on the main frame, as by means of adjusting screws 22. The shaft 18 has pulleys 23, fast thereon for .driving the same. The lower cutter-head is on a shaft 24 which rotates in bearings 25 in the main frame, and has pulleys 26 fast thereon for driving the same. The side-heads 13, 14, are respectively secured to side-head shafts 27, 28, journaled respectively in bearings 29 of side-head hangers 30, 31, adjustable crosswise in the main frame on cross-guides 32, 33, the adjustment for the side-head hanger 30 being eected by an adjusting screw 34, and the adjustment for the side-head hanger 31 being effected by an adjusting screw 35 in any usual or desirable manner. 'Ihe sidehead shafts 27, 28, respectively have pulleys 36, 37, fast thereon for driving the same. The feed-rolls are driven by suitable trains of gearing from a feed-roll drive-shaft 38, which in the present exemplification has a pulley 39 tight thereon and a pulley 40 loose thereon, the shaft being journaled in bearings 41 on the main frame.

The instrumentalities I have so far described are shown in or supported on the main frame of the machine.

51 is a countershaft frame, which is a frame separate from and spaced from the main frame of the machine, as shown by the space 52 between said frames. This construction enables me to make the main frame of the machine as a solid casting and to make the countershaft frame of the Inachine also as a solid casting, providing eX- ceptionally rigid structures which I have found especially desirable in high-speed machines of the character stated,vand to space the frames apart for such distance as may be required by the character of work perg Y Y 1,135,411

formed or permitted by the space allowed in which to set up the machine as a whole, the space 52 kbeing longer er shorter, dependent on the requirements .or conditions. 'A countershaft 53 is mounted on the 'countershaft frame. The countershaft has pulleys 5d@ fast thereon, which coperate with the pulleys 23, on the 4upper cutter-head shaft, the said pulleys having belts 55 received thereabout. The countershaft further has pulleys 56 fast thereon, which cooperatev with the pulleys 26 on the lower cutter-head shaft, beltsV 57 being received about said pulleys for driving said lower cutter-head shaft, the said belts being shown as half-twist belts. A preferably wide faced pulley 58 is secured to the countershaft for cooperating with the pulleys 36, 37, on the side-head upright shafts, belts 59, 60, being received over said pulley 58 and the respective pulleys 36, 37, these belts being preferably quarter-twist belts oppositely twisted for rotating said side cutter-heads in opposite directions. The countershaft Afurther has a pulley 61 fast thereon, which coperates with the pulleys V39, L10, on the feed-roll drive-shaft, the pulley 61 being preferably a wide faced pulley for permitting lateral shifting of a feed belt 62 received about said pulleys. l

The countershaft, in the present exemplification, is `arranged to rotate in the direction of the arrow a, and is driven by a belt 63 received over a pulley 64 fast on said countershaft. Other driving means may however be provided for driving the countershaft. VSubstantial and economical means Vare provided for mounting said countershaft on the countershaft frame and for alining said countershaft with the horizontal cutter-head shafts, and for moving said counter-shaft bodily toward and from the main frame for taking up excessive stretch `in the belts between the countershaft and the pulleys on the main frame. The countershaft rotates in hearings 71, respectively composed'of a solid part 72 and a removable part 7 3, the removable part or cap being secured to the solid part by bolts 74. (See Fig. Ll.) The bearings are mounted on slides 75 and are adjustable on said slides by means of bolts 7 6, shown in the form of pivot-bolts threaded in threaded bearings 77 in the tines 7 8 o f-overhanging yokes 79 resp'ectively on the vslides 7 5.,V The ends of the bolts are'received in soclets180 located at fopposite Asides ofthe solid parts 72 ofthe bearings, jam-nuts 81 securing Vthe said Vbolts in vadjustedpositions. This constructionrinsures that no strain or pressure shall be'exertedupon the caps or removable parts 73 of the bearings, thereby avoiding heat- Y ing'of the bearings and insuring true run- -ning of the countershaft. Each of the slides 7 5 is provided with a stem 82, shown as a turned stem in the form of a trunnion, which has slide-connection in a bore 83, exemplied as a trunnion-bearing in the countershaft frame. The stems and bores extend in directions toward the main frame and the cutter-head and feed-shafts located therein, for adjusting the countershaft toward and from said main frame and cutter-head and feed-shafts in the main frame. The adjustment is accomplished by means of adjusting screws 81- having threaded connection in threaded bearings 85 in the end walls of the bores 83, the said adjusting screws being received against the ends of the stems 82 for adjusting said stems lengthwise so in said bores, jam-nuts 86 locking the adjusting screws in adjusted positions. The pull of the belts exerts pressure lengthwise of said stems 82 toward the main frame, the said adjusting screws acting as stops for 85 said stems. The stems and the bearings extend substantially across the length of the countershaft frame, whereby the distance between said countershaft on said countershaft frame and the shafts on the main 90 frame driven thereby can be substantially changed for taking up the stretch of the belts.

Tightener pulleys 91 are arranged to bear upon the belts 55 for the upper cutter-head 95 shaft. Tightener pulleys 92 are arranged to bear upon the belts 57 for the lower cutterhead shaft. Tightener pulleys 93 are arranged to bear upon the belts 59, 60, for the side cutter-head upright shafts. The tightener pulleys 91 are mounted on studs 94, secured in bearings 95, in the ends of arms 96, swinging on bearings 97, on studs 98 at the respective sides of the countershaft frame, secured in bearings 99 in the coun- 105 tershaft frame. The tightener pulleys 92 rotate on studs 100, secured in bearings 101 on arms 102, which swing on bearings 103 about the studs 98. The tightener pulleys 91, 92, at the respective sides of the countershaft frame operate independently of each other. They are located between, the arms 96, 102, permitting them to be placed close together. These arms are positioned laterally, and means are provided for preventing the undue swinging of the same, whereby contact between the tightener pulleys thereon and the pulleys on the countershaft with which they coperate is prevented, preventing damage or breakage of the parts, upon breakage of belts, or from other causes. The bearings 97, 103, are positioned laterally respectively between the collars 104;, 105, at the respective sides of the countershaft frame. The said collars are rigid on the studs 98. The collars 105 are provided with stops 106. The arms 96, 102, are provided with stops 107, arranged to coact with the stops 106, for limiting the swinging movements of said arms. These stops are located adjacent to the pivotal axes of said arms, whereby the jolt upon accidental swinging of said arms is lessened.

Each of the tightener pulleys 93 rotates on a stud 108, secured as by a set-bolt 42, in a bearing 109 on an arm 110. (See Figs. 6, 7 and 8). Endwise movement of the tightener pulley on its stud is prevented by a shoulder 43 on the stud and the bearing 109. Each of the .arms 110 is pivoted by a bearing 111 on a sleeve 44. These sleeves are slidable longitudinally on a shaft 112 secured as by set screws 45, in bearings 113 in the countershaft frame. Said sleeves are prevented from rotating on the shaft, as by spline-connections 46. Each sleeve has a shoulder 47 at one end and a collar 48 fast thereon at its other end for holding the respective bearings 111 on said sleeves. Each arm 110 has a stop 49 thereon with which stops 50 on the respective sleeves cooperate for limiting descent of the pulleys 93 and for preventing these pulleys from striking any of the adjacent parts upon breakage of a side-head belt. The studs 94 have shoulders 66 thereon, the tightener pulleys 91 being prevented from longitudinal movement on said studs by said shoulders and the bearings 95. (See Fig. 9). The studs 94 are secured in the bearings 95 as by bolts 67. The studs 98 on which said arms are pivoted are secured in the bearings 99, as by bolts 68. Each of the studs 100 has a shoulder 69 thereon (see F ig. 9), the tightener pulleys 92 being prevented from longitudinal movement on said stud by said shoulder and the bearing 101, the stud 100 being secured in the bearing 101 b y a set-bolt 70. The collars 104, 105, are shown secured to the studs 98 respectively by set-bolts 87, 88. The arms 110 have sidecheeks 114 depending therefrom respectively, the side-head belts being received between said cheeks.

Upon lateral adjustment of either or both of the side cutter-head hangers, the end of the belt at the adjusted hanger will be adj usted laterally with the hanger. The tendency of the belt upon rotation of the pulleys is to adjust itself upon the countershaft pulley to a position in line with the pulley on the side-head shaft, whereby contact between said belt and one of said side-cheeks is effected for moving the belt-tightener arm laterally along its pivot-shaft, and for locating the tightener-pulley in the line of said belt between the countershaft pulley and the side-head pulley thereof, causing continuance of contact between the tightener-pulley and said belt. The tightenerpulley acts upon the slack stretch of the belt, and the positioning wings are acted upon by the tight stretch. of the belt between the countershaft pulley and side-head pulley.

-A tightener-pulley 115 acts upon the feedthe countershaft.

tdt

belt 62. It rotates on a stud 116 journaled in bearings 117 of a shifter yoke 118 having an arm 119 rigid therewith which has a bearing 120 pivoted upon the journal-end 121 of a longitudinally shiftable rod 122 shiftable lengthwise in bearings 123 in the main frame.

The shifting of the rod is effected by a bell-crank lever 124 pivoted on a bolt 125 in a bracket 126, on the countershaft frame. One arm of the bell-crank lever has articulation with said rod, shown as a slot 127 in the end of said arm in which a pin 128 on said rod is received. The slot 127 may be sufficiently long to accommodate different lengths of the space 52 between the main frame and countershaft frame. A link 131 has articulation 132 with the other arm of said belLcrank lever, and has articulation 133 with an arm 134 secured to a rock-shaft 135 journaled in bearings 136 in said countershaft frame and having an operating arm 137 extending therefrom at the side of the countershaft frame. The said operating arm has an extension 138 extending from the opposite side of said rock-shaft, forming an operating lever.

139 is an operating lever pivoted on a bolt 140 to the main frame and located at the feeding-out end of the machine. A link 141 is articulated with the operating lever 139 at 142, and with the operating lever at the counter-shaft frame by an articulation 143, whereby the feed-belt may be shifted by the operator at a position at the ends of the countershaft frame or at a position at the side of the main frame, the link 41 extending across the space 52 between said frames. The link may be made adjustable in length to accommodate different lengths of said space, as by making the link in two parts having adjustable connections between them, shown as bolts 144 received through selective holes 145 in one of said parts and threaded into the other of said parts. The arms 96, 102, and 110, with the tightenerpulleys thereon, extend into the lateral pro jection of said space between the countershaft frame and main frame.

The space between the countershaft frame and main frame may be of such length as the character of work to be done requires or the space within which the machine is to be set up will permit. The said space is bridged by a feeding-in table 151, which comprises a guide-way part 152, secured to the main frame, as by bolts 153, and a guideway part 154, secured to the countershaft frame, as by bolts 155, and a grating-part 156 between said frames, as well as a forwardly overhanging part 157 overhanging I have shownmeans for adjusting the length ofthe feeding-in table, shown by constructing the grating-part of bars V158, 159, whose adjacent ends are adrjustable lengthwise of each other by slots 160 in the bars 158 and `bolts 161 received through said slots and having threaded connection in theV bars 159.v Vhen the main frameV and countershaft frame have been properly relatively placed on the floor or foundation, they are arranged toV be rigidly secured in rplace respectively by bolts 16:2, 163.

A side-guide 165 for the material fed through the machine by the feeding means is provided. It extends across the space between the countershaft Vframe andthe main frame and is adjustable laterally on both of said frames, as by means of a T-bolt 166 re-V ceived in a T-slot 167 in the guide-way'part 152 and clamped to saidV guide-way part by a jam-,nut 168,"and lby a T-bolt 169 Vmovable vlaterally in a T-slot 170 in the guide-way part 154, received through a slot 171. in said side-guide, and clamped in adjusted position thereon by a jam-nut 172. A side-contact arm for the material fed against said vguide is provided in order to contact said material and push 'the saine toward said Y guide at a point closely adjacent to the feeding-in rolls 15, 16. I mount this arm above the countershaft frame and locate its contact-part above the main frame. The arm is shown as comprising a bellscrank lever i. 175 pivoted on a bolt 176 at the top of the countershaft frame, a spring-arm 177 extendingfrom said bell-crank lever, Yone end thereof being received in a socket 178 in said lever, in which it is adjustable lengthwise and clamped in place by clamp-bolts 179 received through slots 180 in said ,spring-arm and having threaded connection with the bell-crank` lever. A contact-roller 181 is journaled on a stud 182 in the said arm above the main frame, at which point said roller contacts the material for pushing the same against the side-guide. For adjusting the kcontact-arm I provide an adjusting screw 183 pivoted on a bolt18i1 on the countershaft frame and having threaded connection with an adjusting wheelV 185. The `adjusting wheel has a collar 186 about its hub 187, held in place lengthwise by a collar 188. The hub rotates in the collar 186. Thisvcollar has j the bell-crank lever '1 5 by pivot-bolts 189.
